EXAMPLE III
Referring to fig. 2, fig. 2 is a flowchart illustrating another voice wake-up method provided in the present application, and the following description is provided with reference to steps S310 to S350.
Step S310: setting a preposed secret word.
In the embodiment of the present application, the preposition phrases can be set in the following two ways: in the first mode, a preposed secret is set by default according to a factory value; in the second mode, the preposed secret words are freely set according to the requirements or the preferences of the user.
It should be noted that the preposed hidden words are freely set according to the requirement or preference of the user, and specifically: the method comprises the steps that a user sends a hidden voice command such as 'opening door by sesame' to a terminal device according to own preference or habit, an audio acquisition chip of the terminal device acquires that the user is a pre-hidden signal, the audio acquisition chip performs analog-to-digital conversion data processing on the acquired voice signal and stores the voice signal after data processing in a database of the terminal device, and when the voice signal needs to be matched with the hidden voice command, related data of the pre-hidden signal stored in the database of the terminal device is directly called.
Step S320: and monitoring a blind voice command.
In the embodiment of the application, when the audio acquisition chip of the terminal equipment acquires a dark language voice command of a user, the audio acquisition chip records the dark language voice command of the user and performs analog-to-digital conversion data processing on the recorded dark language voice command.
Further, when a dark language voice command is monitored, it is also necessary to determine whether the dark language voice command is an effective voice command. The valid voice command is a voice command which can be recognized by an audio acquisition chip of the terminal equipment.
If the voice command is valid, the control terminal device executes corresponding action according to the voice command;
otherwise, the voice command is fed back to the user to be invalid, and the user sends out the blind voice command again according to the feedback.
Step S330: and judging whether the monitored dark language voice command is matched with a preset preposed dark language.
In the embodiment of the application, when the monitored dark language voice command is matched with the set preposed dark language, the terminal equipment is controlled to enter a pre-awakening state according to the dark language voice command;
and when the monitored dark language voice command is not matched with the preset preposed dark language, monitoring the dark language voice command again.
Step S340: and monitoring a wake-up voice command.
In the embodiment of the present application, when the wake-up voice command is monitored, it is further required to determine whether the wake-up voice command is a valid voice command. The effective voice command is a voice command which can be recognized by an audio acquisition chip of the terminal equipment.
If the voice command is valid, the control terminal equipment enters an awakening state according to the awakening voice command;
otherwise, the voice command is fed back to the user to be invalid, and the user sends out the blind voice command again according to the feedback.
Step S350: and entering a wake-up state, and feeding back the terminal equipment entering the wake-up state to the user by voice.
It should be noted that, when the terminal device controls the terminal device to enter the pre-wake-up state according to the whisper voice command, if the wake-up voice command of the user is monitored within the set time, the terminal device enters the wake-up state according to the wake-up voice command of the user; and if the awakening voice command of the user is not monitored within the set time, the terminal equipment enters a sleep state. For example: the set time is 5 seconds, after the terminal device controls the terminal device to enter a pre-awakening state according to the secret voice command, if the awakening voice command of the user is monitored within 5 seconds, the terminal device enters the awakening state according to the awakening voice command of the user; and if the wake-up voice command of the user is not monitored within 5 seconds, the terminal equipment enters a sleep state.
To sum up, this application matches the secret language voice command that will hear with the leading secret language of predetermineeing through setting up leading pronunciation, and when the secret language voice command that hears matches with the leading secret language of predetermineeing, according to secret language voice command control terminal equipment entering awakening state in advance, when terminal equipment gets into awakening state in advance, carry out the pronunciation awakening to terminal equipment to realized awakening up to terminal equipment according to that user's needs are accurate.
The scheme provided by the application is simple to operate, does not need to additionally increase the cost, and obviously reduces the probability that the terminal equipment is mistakenly awakened.
